Abstract :

Background & Objectives: In the present study we Compared effect of drugs & their combinations on the onset & duration of sensory & motor anesthesia and analgesia in supraclavicular achial plexus block. Methods: This was randomized double blind study conducted in 80 ASA I and II patients aged above 18 years with the minimum weight of 40 kgs undergoing surgery of upper limb. Grouping of Patients: 80 patients were divided into four groups on random basis with each group having 20 each:– Group 1 – Received injection lidocaine 2% (5mg/kg) with adrenaline 1 in 2,00,000 and diluted up to 30ml in 0.9% saline solution. Group 2 – Received injection lidocaine 2% (5mg/kg) with adrenaline 1 in 2,00,000 with morphine 5mg and diluted up to 30ml in 0.9% saline solution. Group 3 – Received injection lidocaine 2% (5mg/kg) with adrenaline 1 in 2,00,000 with verapamil 2.5mg and diluted up to 30ml in 0.9% saline solution. Group 4 – Received injection lidocaine 2% (5mg/kg) with adrenaline 1 in 2,00,000 with verapamil 2.5mg and morphine 5mg and diluted up to 30ml in 0.9% saline solution. The relevant data were noted and observed data compiled and analyzed statistically using ANOVA test. Conclusion: In short the verapamil prolongs the duration of sensory anaesthesia and also analgesia and morphine prolongs the analgesic duration of lidocaine, when these drugs were used as adjuvants to the local anaesthetic with minimal side effects
